Been bouncing between Wizordum and Void Stranger over the last few days. Wizordum is a fun "boomer shooter" that takes a lot of inspiration from games like Hexen and I've been enjoying mowing down monsters with fireballs and a magical shotgun. Void Stranger I'm still not sure how I feel about. Heard it mentioned a few times as a very meta game with a lot of layers. In theory I like games like that. Figuring out the core puzzle gameplay of moving blocks around has been fun, even if I don't consider myself that great at puzzles, but the meta stuff is riding that fine line between being just cryptic enough to be intriguing to being so cryptic that I'm not sure how I'm supposed to figure this out without a guide.

Maybe a dumb suggestion, but since you mentioned older systems, Castlevania: Symphony of the Night is a PS1 classic that helped create the Metroidvania genre. There's also Bloodstained: Ritual of the Night, which is a spiritual successor by one the key developers behind SOTN. Dead Cells and Hollow Knight are solid games that have been recommended already, but if you find yourself enjoying the rogue-lite elements of those you might enjoy Cult of the Lamb. Admittedly it's top down 2.5d, but it's a nice blend of rogue lite and town management as your tasked with building up a cult and turning it into a thriving community in between fighting your way through dungeons.
